STUFFING-IBOZ GLAND.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Application filed June 17, 1909. Serial No. 502,728.

To all whom it may concern:

lie it known that I, Fnnusmcn Keenan, a citizen of the United States, and a residentof White Plains, in the count of Wesb chester and State of New Yor have invented a new and Improved StufiiIig-Box Gland, of which the following is a full,clear, and exact description.

The invention belongs to that class of stuilin -box glands which are constructed of separa le sections to enable the removal of the gland from the piston rod without the necessity of disconnecting the rod from the cross head.

The invention has in View a. gland of this character in which the sections interlock with each other and are held against relative movement in any direction, the bolts or studs for forcing the gland into the stallingbox also serving to force the inner end portions of the sections of the gland together.

Reference is to be had to the accompanying drawings forming a part of this s ecifioation, in which similar characters 0 reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal section through a stalling-box of a cylinder having my improved land; Fig. 2 is an outer end view of the g and; Fig. 3 is an inner end view of the land, with the sections thereof separated; ig. 4 is a side view at the gland, with the scctions'separated; and Fig. 5 is an inner face view of one of the land sections.

For the purpose of illustrating the nature and ap licalion of my improved stufiin box, 1 li ave shown a cylinder 5 having t c usual stalling-box 6 through which the piston rod 7 passes.

My improved gland for compressing and holding the parking in the box is constructed with a body portion 8 having an internal bore of a size to snugly lit the piston rod 7 and an external diameter to likewise [it within the stalling-box 6, the body having an intermediate flange 5) provided with the usual openings 10 to receive the studs or bolts 11 for forcin" the gland into the box.

The body and flange of the gland are divided longltudiua-lly into two separable half sections, the outer end porlion o one of said ol-lions having :1 lug or ldnck 12 formed integrally or otherwise rigidly attached to its body or boss portion all each side, ouch lug extruding hoyond the inner edges of. the gland sections, with lho. outer and inner faces arranged concentrically with respect to the body 8, as clearlv shown in Figs. 2 and 3. The inner side edge of the extended ortion of each lug is provided with a notc 13 which is designed to receive a similarlyshaped projection 14, integral or otherwise ri dly secured to the other gland section a jacent to the inner ed es thereof, as shown in Figs. 1, 3 and 4. hat portion of the body of the gland at the opposite side of the flange is provided on the inner edges of one land section (shown to be that havin the ugs 12) with V-shapcd grooves 15; and the inner and abutting edges of the other gland section have counterpart tongues 15', this construction of the joint between the gland sections obviously preventing the working of one gland section on the other when the two sections are secured to than To secure-the gland sections against relalive lon itudiual movement I provide straps 16, whic l are rcmovahly secured at each end to the flange 9 by screws or other suitab devices 17, the straps being arranged to overlie the joint at up osite sides of the gland sections, and prei erably let into re cesses formed in the flange, whereby the screws 17 will be relieved of strain and the straps prevented from working laterally.

With the several parts of the gland detached, the gland is applied by placin the two sections against the piston rod, wit 1 the section having the projection 14, arranged inwardly between the stnlling'box and the other gland section. One or both of the gland sections are then slid on the rod to carry the projection 14 into the notches 13 of t ic lugs, and both sections passed within the stalling-box, with the studs passing through the openings 10 in the flange 9. The straps 16 are then applied and the nuts of the studs tightened to compress the ackiug in the box. The pressure on the angc incident to the tightening of the stud nuts forces the tongue and grooved portion of the joint between the gland sections securely together, the separation of the outer 10rlious of lhe gland sections being resisted by the lugs 12 and projections H, lhus cll'cctually preventing the gland scclious from working on each other during the action of the piston rod.

Having thus dcseribml my iuvuuliou, I claim as now and desire lo secure lay Letters Patent:

1. A glnud divided lougihuliually into Ill] separable sections, a lug rigid with one section of the gland and "wing anotch, and a proi'ection carried by the other section of the g and and arranged to move into and out of said notch by a relative longitudinal movement between the land sections.

2. A. gland divided ongitudinally into separable sections and provided with an intermediate flange, the land SHJUODS at the inner side of the flange aving a tongue and grooved joint, and means to prevent the lateral separation of the two sections of the land, arranged at the outer side of the flange to be en aged by a relativelongitudinal movement tween the glandsections.

3. A gland divided longitudinally into separable sections and having an intermediate flange rovided with recesses in the edges at ear: side, with the recesses extending over the joint between the two land sections, and straps securing the glan sections together, detachably secured to the flange and fittin within said recesses.

4. A g and divided longitudinally into separable sections, lugs extended over the joint between the sections of the gland, with each lng ri 'd with one of the gland sections and provi ed with notches in its inner side edge, and projections adapted to pass into an out of the said notches and secure the sections-of the land against lateral separation, with eaci projection carried by the oppos te gland section to that carrying its engagmg 8- 5. A gland having a bod portion pro vided with an intermediate 1 n c with the flangc and body portion divid longitudinally into separable half sections, and llOi/JllOd lugs and projections, with a In and a projection arranged at each side 0 the flange, each of said lugs being rigid with the body ortion of one of the gland sections, each 0 said projections being rigid with the body portion of the opposite land section and arranged to more into am out of the notches of the lugs by a relative longitudinal movement of the gland sections, and the body portion of the gland sections at the opposite and inner side of the flange having a tongue and grooved joint.

6. gland divided lon itudinallv into separable half sections and provided with an intermediate flange, means at the outer side of the flange to secure the gland sections against lateral separation and arranged to move into and out of engagement by a relative longitudinal movement between the gland sections, and stra s to secure the gland sections against ative longitudinal movement, dctachably secured to the flange.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnwses.
